by 30 %.
Incorporation of CNTs enhanced
electron flow associated with photosynthesis
by 49 % in extracted chloroplasts and

by an incoming photon, producing no photon along the way and
leaving too few excited
electrons to make laser light.

electron was detected
by the infrared laser pulse as soon as it
left the atom in response to the excitation
by XUV light.
These accelerators work
by shooting pulses of intense laser light into plasma to create a wave rippling through the cloud of ionised gas,
leaving a wake of
electrons akin to those that form behind a speedboat in water.

by Hirst from the Science Photo Library, is a coloured scanning
electron micrograph of a biopsy from the intestine of a child with small bowel cancer.
How an
electron interacts with other matter depends on which way it's spinning as it zips along — to the right like a football thrown
by a right - handed quarterback or the
left like a pigskin thrown
by a lefty.
This «pseudogap» looked like the one
left by superconducting
electrons, but it showed up at temperatures too warm for superconductivity to occur.
A buckyball (top) can be ionized either
by removing an
electron (bottom
left) or with the new superacid (bottom middle), producing a protonated buckyball (bottom right).
A new technique enables 3 - D visualization of chromatin (DNA plus associated proteins) structure and organization within a cell nucleus (purple, bottom
